The STEP5 function interpolates between two markers using a quantic polynomial. Generally, this function is used when linking two markers in a gradual curve.

Arguments definition
|
|
The input variable for the defined STEP5 function •Generally, this variable is time or a function that returns a real number. |
|
|
The starting point of the STEP5 function |
|
|
The initial value for the input variable (within the range of x≤x0) |
|
|
The ending point of the STEP5 function |
|
|
The initial value for the input variable (within the range of x≥x1) |
Formulation
Example
STEP5(time, 1.0, 0.0, 4.0, 1.0)
•x = time: Independent variable
•x0 = 1.0: X-value at which the STEP5 function begins
•h0 = 0.0: Initial value of the STEP5 function
•x1 = 4.0: X-value at which the STEP5 functions ends
•h1 = 1.0: Final value of the STEP5 function
